Study showing Copper Infused Pyjamas versus Standard Hospital Textiles
The average stay in a UK hospital is 7 days1, where the main clothing of the in patient is
pyjamas. It has been emphasised that microbial shedding from our body occurs all the time and
is greater in patients2. The moisture and temperature in the textile micro-environment promote its
proliferation when a bacterium is shed into a textile fabric between the patient and the bed, either
on the pyjamas or directly onto the sheet3. Pyjamas are the main barrier covering your skin area,
where we are most at risk of contracting a HAIs or Nosocomial infections, through broken or
compromised skin4, also well known is that people can contract MRSA from dust containing
contaminated skin particles that may be carrying bacteria on it5. Nosocomial infections can affect
any part of the body but 24.3% of all nosocomial are through the skin or surgical wound site6
(see Appendix B).
Micro-organisms enter the tissues of the skin and other body tissues, often at the site of
compromised skin such as a sore, ulcer or a cut, to cause symptoms such as redness, swelling
and/or pus7. Several studies
8-9,10
indicates that people are most at risk of serious infections
include:
1. Elderly people (due to dermatological changes)
2. People with wounds or abnormal skin sites
3. Those whom are already ill may have lowered immunity or being immunosuppresed
4. Those that are already carrying staphylococcus aureus or MRSA
5. Those that are hospitalised for a length of time
6. Surgery
7. Diabetics
8. Previous anti-biotic use
9. Previous MRSA colonization

MRSA exists throughout the community, it is more common in hospitals where people are
having medical procedures and are being cared for. Recent research also shows that nasal MRSA
carriage in diabetic patients is a significant risk factor for foot ulcer MRSA infection10
. MRSA
infection occurs when the bacteria enter the body through a wound, or when the bacteria enter
the bloodstream11
. Cross infections are not always the cause of MRSA, as bacteria can enter the
body through a wound or any compromised skin. S.aureus is just one of a family of
staphylococcal bacteria. Their normal home is on human skin and nose, and some of them, such
as S. epidemidls- are seen as part of the normal commensal flora of the human body12
. About
30% of the general population are colonised by S. aureus. A carrier can be a source of infection
for themselves (e.g. they can infect themselves if they have a wound), especially those with a
compromised immune system, or those on immuno supresents, but they can also infect others
when the bacteria are passed on either on someone’s hand (normally a healthcare worker's) or on
infected equipment13
. In about one tenth of these carriers (3% of the population overall), the S.
aureus is MRSA. Carriage sites are most commonly the nose and the skin, especially in folds
such as axilla (armpit) or groin14
.
It is estimated that approximately 70% of older people in the UK experince skin problems, many
of which are preventable15
. Age-related changes in the skin mean older people are at increased
risk of skin breakdown and should be supported to maintain good skin health16
.
Copper complexes and copper fabrics which deliver copper ions are well known to be used in
wound healing, and angiogenesis (VEGF) is believed to be the most prevalent. VEGF expression
is sensitive to copper ions and that the angiogenic potential of copper may be harnessed to
accelerate dermal wound contraction and closure17
. As well as rejuvenating skin texture. Copper-
sensitive pathways regulate key mediators of wound healing and skin rejuvenating such as
angiogenesis and extracellular matrix remodelling. Copper-based therapeutics (copper ions)
represents a feasible approach to promote dermal wound healing18
(see Appendix D). A sufficient
level of copper appears to be required for angiogenesis. Copper availability has played a
fundamental role in growth regulation throughout evolution and that is the reason that so many

Borkow, et al20-p(610)
. summarised the importance of copper, stating that:
"Copper is an essential trace element involved in numerous human physiological and metabolic
processes. It plays a key role in many of the processes that together comprise of wound healing,
including induction of endothelial growth factor, angiogenesis and expression and stabilization
of extracellular skin proteins".
Copper as opposed to silver (which has now had its anti-microbial status withdrawn in the
USA21
) is essential for the normal function of many tissues, gene expression and many metabolic
processes22
. This study shows that copper fabrics continuously kill disease causing microbes23
. It
is shown that just 2.3% copper oxide impregnated polypropylene nonwoven fabric and the
internal copper contained within the fabric both release Cu++ ions (containing 3% copper oxide
plated fibres) of test dressings have, potent antibacterial and anti-fungal properties. The damage
to micro-organisms is exerted within a matter of minutes of their exposure to the copper
containing fabrics24
. Although most hospitals provide pyjamas of normal cotton, these are not
known to prevent the spread of nosocomial infections, where as copper fabrics have the ability to
kill pathogens25
. Copper fabric should be used as close to the skin as possible for effective, odour
control, improved hygiene and promote healthier skin tone and texture26
.
Bamboo, which is the fastest-growing plant and requires no pesticides, is touted as an
environmentally friendly material. Lab results show that bamboo fabrics is more than 9 times
more effective at killing bacteria than fabrics treated with chemicals to kill bacteria, even after 50
commercial washings27
.
The bamboo and copper infused pyjamas should be provided to supplement other hospital
protocols and become part of an overall risk management program to control HAIs. Another
advantage over the cotton hospital supplied pyjamas or pyjamas brought from home (not known
when last laundered) is that the copper ions released by the copper plays an essential role in

angiogenesis28
(the growth of new capillaries). Capillaries are designed to provide maximum
nutrient efficiency so as an increase in the number of capillaries allows the micro-circulation
network to deliver more nutrients and oxygen in the same amount of time. The greater number of
capillaries allows for greater oxygen exchange, feeding the skin and preventing dry cracked skin
by the rapid promotion of collagen and elastin, which in turn dramatically helps rehydration of
the skin and can aid in the prevention of skin pathologies29
. Angiogenesis in turn can help to stop
the skin from being further compromised and skin rejuvenating30
, reducing the patient's chance
of contracting MRSA through open sores, broken skin or other skin pathologies, especially those
in wards for longer periods31
. Another preventive modality would be for those who are going to
hospital for elective surgery (especially those who have skin pathologies) could wear these
pyjamas as normal at home prior to hospitalisation, this would promote healthier skin tone and
texture through (angiogenesis). Copper demonstrates a critical effect in the processes of wound
healing, including induction of endothelial growth factor, angiogenesis, antimicrobial potency
and expression and stabilization of extracellular matrix32
. And would ensure the decolonisation
of microbes33
. It is also known that the bacteria can delay dermal healing by competing with host
cells for already depleted nutrients and oxygen. MRSA may remain as reservoirs on hospital
equipments, for example, beds, which is a particular issue where pressure or diabetic ulcers are
common. It is important to remember that chronic wounds often develop due to an alteration in
blood-flow (micro-circulation) to the infected area, and the use of systemic antibiotics has very
little or no affect on the wound site as the reduction of the capillaries that were able to deliver
blood are sometimes broken, split or withdrawn, this can prevent access of the antibiotic to the
affect area34
.
Our copper and bamboo pyjamas that give off copper ions (see Appendix E), have potent anti-
fungal and anti-bacterial properties, which will totally destroy micro-organisms and will not
allow them to mutate or even enter the VBNC state35
. They can also promote angiogenesis,
rejuvenated skin and can be produced with an anti-static finish (which will repel dust). As dust
and skin cells are known to carry MRSA36
.
Most importantly, copper infused fabric costs just a fraction more than cotton fabrics alone.

Ladies and Men's Pyjamas
We recommend daily use, as the pyjamas are designed around a breathable fabric that can be
worn 24 hours a day. Additionally, the pyjamas should be worn as much as possible both in and
out of bed, and close to the skin as possible. When at risk of a nosocomial infection or otherwise
as normal in bed.
39.3% copper fibre content and 60.7% bamboo viscose are very coefficient materials which we
have bought together and manufactured into male and female bed wear, pyjamas. Humans are
very tolerant of copper and it is in many different foods, nearly all vitamin tablets, and is easily
metabolised and utilised by the body when absorbed either orally or through tissues37
.
Human skin, in contrast to micro-organisms, is not sensitive to copper and the risk of adverse
reactions due to dermal exposure to copper is extremely low. Copper is not only considered safe
for humans, as demonstrated by the widespread and prolonged use of copper intrauterine devices
(IUDs) by women38
. Additionally, bamboo fibre’s natural anti-bacterial qualities do not cause
skin allergy as chemical anti-microbial sometimes can. Besides, copper and bamboo fabrics are
known to be safe, copper fabrics have passed standard allergencity and skin irritation test which
have been shown to be safe for using fabrics for personal use by the Environment Protection
Agency of the USA with registration number 84542-639
.
The Pyjama fabric has been the subject of 50 commercial wash cycles with no special detergents
or bleaching type agents keeping a normal PH level of 6.2 and at a water temperature of only 21
degrees carried out by accredited lab (ATTC 10231).
Copper fabrics in vitro tests showed them to be anti-microbial with significant log reductions
with very little or no leaching (see Appendix F: In Vitrol Anti-microbial Certificates).
What is it that is innovative/new?

Copper and its anti microbial properties are neither new nor innovative, nor are infusing acrylic
fabric with Nano copper.
What is new is the way the copper, polyester and bamboo (viscose) have been infused and
engineered to be a breathable fabric, so comfortable and non clammy. The methodology of
manufacture, i.e. the bringing together in one fabric, two coefficient fibres for both a practical
and very functional use.
Our fabric is now used on a daily basis by the Chinese military with over 4 million troops having
socks, underwear and towels etc. There has NOT been one report of dermal intolerance (both
male and female).
Also the Army in the USA has standard issue Cu29 infused socks, being nearly 2 million people.
These are issued not only for the anti microbial properties alone, but for the preventative
modality of foot skin pathologies or when skin in that area is compromised an infection is far
less likely.
NASA journey to international space station has chosen copper infused garments, socks,
underwear, T-shirts, towels, bed sheets, etc., not only will this decrease the weight from nearly 1
ton estimated of standard fabrics, down to a fraction of this weight. The study showed that the
garments were totally anti-microbial and more comfortable to wear than the previous garments36
.
The pyjamas are new and innovative by British design, also what is relatively new is the
functionality of anti-microbial, anti-static/ anti-dust and promotes angiogenesis which can
enhance wound closure, skin rejuvenation, promotion of collagen and elastin and are anti-odour.
How will this product contribute to reducing hospital acquired infections?

One of the problematic HAIs is MRSA or VRSA which is transmitted by touch but very quickly
mutates and becomes resistant to its surroundings40
. There is no evidence that microbes would
become resistant on copper. Horizontal gene transfer (HGT) is largely responsible for increasing
the incidence of antibiotic-resistant infections worldwide. In addition, rapid death of both
antibiotic-resistant strains and destruction of plasmid and genomic DNA were observed on
copper, which could be useful in the prevention of infection spread and gene transfer41
.
The Cu and Bamboo pyjamas will act as a barrier both for the staff handling of the patient, as
microbes live on fabric surfaces and there for mutate. These pyjamas will not allow the microbes
to survive and completely destroys them, within minutes without chemicals by the exposure to
copper ions that penetrate the harmful bacteria/ fungus destroying the DNA42
.
The microbes cannot become copper tolerant on the fabric containing copper fibres that produce
copper ions43
.
For the patients, especially those with compromised immune functionality or those who are
immunosuppressed can easily contract a HAI just through their own skin flora44
. Those whom
are hospitalized for longer period of time would also benefit from the angiogenesis process
which plays a central role in wound healing and also accelerate the healing of any dermal skin
pathologies and wound contraction and closure45
(providing the pyjamas cover the area of skin).
Those whom have a breech in the skin (for example, bed sores, ulcers, or dry cracked skin),
which may become breached just from swelling, pressure sores, or surgical wound sites are at
risk of infection. Skin conditioned with nutrients and oxygenated blood supply from vascular
endothelial growth factor (VEGF) newly formed capillaries in their micro-circulation would
greatly improve skin texture reducing the chance of the patient contracting a HAI in the first
place46
.
The fabric contains approx 2.5-3% copper (Cu++) in 40% of the fibres and have potent
antibacterial, gram- positive and gram negative bacteria and anti-fungal properties. The pyjamas
cover 90% of the body and present a greatly improved modality in the reduction of Skin
pathologies (by way of Angiogenesis) giving skin rehydration nutrients and oxygen that is
needed for the skins well being. It is well known that copper ions (Cu++) show a pro angiogenic

action favouring the development of new vessels47
, also having a natural ability to destroy
microbes in a very short period of time. Patients shed skin cells and bacteria in their pyjamas, the
temperature and humidity between the patients and the bed are appropriate conditions allowing
for effective bacterial proliferation. We suggest that hospital textiles, especially those that come
in contact with the patients, such as patients' sheets, pillowcases, robes, and pyjamas, are an
important source of micro-organisms, that may infect susceptible patients either by endogenous
transmission, indirect contact or through airborne transmission (dust) when these fabrics are
handled by the hospital staff. The use of pyjamas could reduce prolonged hospitalisation,
decrease the use of antibiotics and the very high costs associated with increased periods of
hospitalisation48
.
Guidelines or protocols to which this product relates
At present, the only guidelines for night wear are to have clear markings on the label keep away
from fire. We recommend that they are not washed with fabric conditioner. The pyjamas only
need to be washed in water 20-25 degrees, no bleach or any substance, likely to be outside
standard recognised PH value between 5-8.
Why is this product more effective in reducing healthcare associated infection than other
similar class of products in the market?
The only comparable product is nano silver fabric, which is not anti-microbial49
. It is been
observed in studies that silver treated cotton fabric leach and have zones of inhabitation that are
least minimum 24mm and maximum 29mm for gram positive bacteria and minimum 14mm and
maximum 18mm for gram negative bacteria50
. Silver fabric has limited durability and has the
potential to cause a variety of other problems when used in garments. As the garments are
washed the silver dosage depletes from its original anti-bacterial state reducing efficiency. If too
little is left in the garments after washing the bacteria colonisation are not controlled and can
mutate, cause rashes and other skin irritation in users51
.
Silver does have anti-bacterial function but the copper as opposed to silver is essential for the
normal function of many tissues, gene expression and many metabolic processes. Copper unlike
silver, is readily metabolised and utilised by the body when absorbed either orally all through
tissues, it is found that in many food types and nearly all multi-vitamins. The R.D.A is 2mg
daily52

Cotton pyjamas or other types of fabric manufactured into night wear (that patient may bring

In our studies, in vitro results showed that in the analysis of antimicrobial properties of fabric
according to ISO 20743: 2007, what was used as a control was clean laundered cotton NHS
hospital gown (standard issue) shows that there is significant log reduction (see the lab results
shown in orange highlight with the Doc. No. COA-FMT-S3678-02). (see Appendix G: NHS
Gown Fabric Versus Copper)
What is the mechanism of action?
The direct effect of destruction comes from the release of copper ions which degrade the
DNA of a cell and inhibit its respiration. The indirect effect is even more rapid. On a dry
surface, copper interacts with the bacteria's metabolism to generate very potent free
radicals, which are even quicker than copper itself at destroying the DNA and inhibiting
respiration53
.
Horizontal gene transfer (HGT) in bacteria is largely responsible for the development of
antibiotic-resistance, which has led to an increasing number of difficult-to-treat healthcare-
associated infections (HCAIs) – copper prevents this process from occurring and rapidly kills
bacteria on contact54
.
Composition of the compound (if applicable) or appropriate information to ensure
assessment of risk and safety:
Viscose bamboo 60.7% and copper infused polyester 39.3% the CTTC report No.: BA13000894,
dated on 15/05/2013.
Copper is known to be very safe and is in fact the only solid surface material registered as safe
and poses no threat to human safety. It has been widely used in water pipes, and copper surfaces
have recently been shown to cut down on nosocomial infections in a four year study at 3 major
hospitals in the USA. By as much as 58%55
(see Appendix H: 58% HAIs Reduction USA Trial ).

Safety information on use of product:
Copper fabrics have widely been studied in one form or another been used around the world
without any known reports of dermal intolerance.
NASA USA, the international space station have spent millions of dollars researching copper
infused garments and have given the official approval that the cosmonauts will wear copper
infused fabrics whilst on the space station57
. Under the H.R.P. Keep astronauts healthy and
functional during deep space, the budget allocated was $ 165 million for 2013.
Also the USA Army of 2 million wear copper socks and the Chinese Army of nearly 4 million
are given copper socks, copper pants, and copper towels (all copper infused fabrics).
In vitro activity of the compound
A U.K.A.S. Laboratory has carried out AATC147 Standard, anti-microbial on MRSA and
Candida. This was carried out 8 times in the UK and twice in a Chinese textile laboratory.
In the UK, we used international standard method EN ISO 2074358
which would stand up the
best to scrutiny as it is an international standard method and the test is performed in triplicate to
remove any element of doubt to the inherent biological variability that comes with any
microbiological method.
a) Absorption method (an evaluation method in which test bacterial suspension is inoculated
directly onto samples);
Samples using method A includes; Laboratory certificate No.: 05042
05043
05044
05228
05229
05230
b) Streak method (an evaluation method in which test bacteria are placed on an agar plate and
transferred onto samples); Laboratory certificate No. 04543

Please note that test No. 05228-05230 have got cotton control results, which show the significant
difference between copper infused fabrics and cotton control (see Appendix G: NHS Gown
Fabric Versus Copper)
Published or other evidence of impact, of product/process on health-care associated
infections:
The pyjamas would be an asset in the fight against HAIs. There is evidence provided within that
MRSA microbes can infect and also cross infect. There is also evidence to suggest that people
are more at risk of getting MRSA in a hospital setting. Our pyjamas were engineered to reduce
the bio burden on a clinical setting or hospital environment by both a preventative modality
healthier rehydrated skin (less likely to get an infection). Also engineered to be anti-static (will
not attract dust or skin cells) demonstrated to carry MRSA. The pyjamas cover a vast area of
your skin flora which in turn kills any microbes, either on your skin or on the fabric which will in
turn reduce cross infection.
